* | win32: simplify spawning appletsRon Yorston2017-07-211-6/+1
| | | | | | | | | | | | | | The original WIN32 code used the BUSYBOX_APPLET_NAME environment variable to pass the applet name to the spawned process. This was based on the (apparently) mistaken idea that WIN32 would replace argv[0] with the path to the executable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based on a patch from Steven McDonald <steven@steven-mcdonald.id.au>: This makes 'unshare --user' work correctly in the case where the user's shell is provided by busybox itself. 'unshare --user' creates a new user namespace without any uid mappings. As a result, /bin/busybox is setuid nobody:nogroup within the namespace, as that is the only user. However, since no uids are mapped, attempting to call setgid/setuid fails, even though this would do nothing: $ unshare --user ./busybox.broken ash ash: setgid: Invalid argument 'unshare --map-root-user' still works, but because Linux only allows uid/gid mappings to be set up once, creating a root mapping makes such a namespace useless for creating multi-user containers. With this patch, setgid and setuid will not be called in the case where they would do nothing, which is always the case inside a new user namespace because all uids are effectively mapped to nobody: $ id -u 1000 $ ls -lh busybox.fixed -rwsr-xr-x 1 root root 826.2K May 21 00:33 busybox.fixed $ unshare --user ./busybox.fixed ash $ id -u 65534 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

* | Use %I64* formats with MinGW instead of %ll* formatsJohannes Schindelin2017-07-181-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The MSVC runtime uses the format specified %I64 for 64-bit data types; It does not understand e.g. %llu for unsigned long longs. However, mingw-w64 provides a compatibility mode in its runtime wrapper which can be activated by defining the constant __USE_MINGW_ANSI_STDIO=1 in which case we must refrain from overriding the %ll* formats. This fixes quite a couple of compile warnings when building with the mingw-w64 compiler. Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>

| * mount: create loop devices with LO_FLAGS_AUTOCLEAR flagDenys Vlasenko2017-03-161-16/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "autolooped" mount (mount [-oloop] IMAGE /DIR/DIR) always creates AUTOCLEARed loopdevs, so that umounting drops them (and this does not require any code in the umount userspace). This happens since circa linux-2.6.25: commit 96c5865559cee0f9cbc5173f3c949f6ce3525581 Date: Wed Feb 6 01:36:27 2008 -0800 Subject: Allow auto-destruction of loop devices IOW: in this case, umount does not have to use -d to drop the loopdev. The explicit loop mount (mount /dev/loopN /DIR/DIR) does not do this. In this case, umount without -d should not drop loopdev. Unfortunately, bbox umount currently always implies -d, this probably needs fixing. function old new delta set_loop 537 597 +60 singlemount 1101 1138 +37 losetup_main 419 432 +13 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 3/0 up/down: 110/0) Total: 110 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

| | | | | | | | | | | | | | | | | | | | Good news that TLS_RSA_WITH_AES_256_CBC_SHA256 still works with new code ;) This change adds inevitable extension to have different sized hashes and AES key sizes.
